From: Thomas Jarosch
To: Ryan C. Gordon Subject: SDL: DirectFB videodriver segfault Date: Sun, 21 Dec 2003 20:40:14 +0100 Hi Ryan, attached is a patch to fix a segfault in DirectFB_VideoQuit. When SetVideoMode never gets called (f.e. wrong command line arguments for "testsprite"), this->screen->hwdata is NULL. Cheers, Thomas --HG-- extra : convert_revision : svn%3Ac70aab31-4412-0410-b14c-859654838e24/trunk%40760
